WordPress：Notice: get_screen_iconエラーの対応方法

get_screen_iconはwordpress3.8移行使われていないようなので、該当箇所をコメントアウトで対応しました。

	if ( WP_DEBUG && apply_filters( 'deprecated_function_trigger_error', true ) ) {
		if ( function_exists( '__' ) ) {
			if ( ! is_null( $replacement ) ) {
				/* translators: 1: PHP function name, 2: version number, 3: alternative function name */
				trigger_error( sprintf( __('%1$s is <strong>deprecated</strong> since version %2$s! Use %3$s instead.'), $function, $version, $replacement ) );
			} else {
				/* translators: 1: PHP function name, 2: version number */
				// trigger_error( sprintf( __('%1$s is <strong>deprecated</strong> since version %2$s with no alternative available.'), $function, $version ) );
			}
		} else {
			if ( ! is_null( $replacement ) ) {
				trigger_error( sprintf( '%1$s is <strong>deprecated</strong> since version %2$s! Use %3$s instead.', $function, $version, $replacement ) );
			} else {
				trigger_error( sprintf( '%1$s is <strong>deprecated</strong> since version %2$s with no alternative available.', $function, $version ) );
			}
		}
	}
